The distribution in different particle size of municipal solid waste incinerator fly ash were studied by sieve method, and the heavy metal content and speciation of Pb, Cd, Zn, Cu, Mn, Ni and Cr in different particles were analyzed by Tessier's sequential chemical extraction procedure. The results showed that more than 90% of fly ash's particle size was less than 250 μm, while particles of 150~250...
An investigation was conducted on the characteristics and leaching behavior of heavy metals from municipal solid wastes incineration (MSWI) fly ash in Chongqing, China. Results indicated that the average particle size of the fly ash was 36.4 μm, the large particles were formed mainly by small particles' adsorption or aggregation. The total content of the main heavy metals was about 1.04% of the fly...
